I've discovered that I can hear it REALLY loudly with my right ear (with a finger jammed in my left ear), and hardly at all with my left ear (w/ my right ear plugged)- clearly due to a difference in my hearing abilities and would explain the wavering 'off' stereoscopic image. Most interesting: if I hum the note, the HUM seems to stop for a moment or two, then immediately fills in the auditory vacuum. It's almost like my humming creates a temporary baffle that mutes or 'defeats' the waves- like noise cancelling headphones.

Last night was quiet enough outside that I could hear it outdoors... I also now remember how loud it was last summer. I'd like to go to other people's homes in the area and see if it can be heard. I'm also considering a late night source search when it gets really bad--- does anyone have any suggestion as to what type of device I might need to detect or measure this sound. If I can get at least 3 accurate measurements I can begin to triangulate the source direction and track it down (this assuming there's a primary direction). I"m under the impression this is an overlapping phenomenon, so I'm sure there are multiple sources--- whether low frequency towers, ELFS or whatever other networking might be causing this. And I can hear it right now, at 10:00 am, in my otherwise silent home.

Laptop, with good mic (like a gigaware combo camera mic), FFT (fast fournier transform) anaylyzer or Spectrum 1/3 Octave band analyzer software. Take data on a spread sheet and track to the epicenter of the intensity. I suggest you locate the high pressure natural gas lines in your area and focus on those before you waste time changing cell towers and the like. The low frequency spectrum carries through the ground and does not attenuate quickly, especially if you are tracking on a fault line or geological rift (like in Taos. FYI the SF Bay area out east past Livermoor is loaded with Hum reports (Topix Livermore), as is the LA area, so finidng a single epicenter will be very difficult.
